DFHTHALMIC IyKC lFNYlJING.

. Application filed November 17 '0 all whom it may concern:

Be it known that I, ELMER ill. SOHU- MACHER, a citizen of the United States, residing at Southbridge, in the county of Worcester and State of'lvlussechusetts, have invented certain new and useful Improvements in Ophthelmi Mountings, ofwhieh the following is a *peeifieetion.

This invention relates to improvements in ophthalmic mountings and has particular reference to what is commonly known as the l/Vindsor mounting; that is to say, it mounting made up of a combination or" me tallic and non-metallic. parts.

One of the leading objects of the present invention is the provision in connection with a mounting of this character, of novel and improved means for readily and securely connecting the metallic and non-metallic portions of the construction.

Other objects and advantages of my iniproved construction should be readily apparent by reference to the following specification taken in connection with the accompanying drawings, and it will be understood that I may make enymodifieutions in the specific details of construction shown and described within the scope of the appended claims Without departingfrom or exceeding the spirit of my invention.

Figure I represents a front elevation of a mounting embodying my improvements.

Fig. II represents an enlarged fragmentary perspective view of a portion thereof.

Fig. III represents a. perspective view of the attaching clip employed in Fl". II.

Fig. IV represents a perspective view of a blank for a slightly modified form of ut taching clip.

Fig. V represents an enlarged perspective view illustrating the use of one of these clips.

Fig. VI represents a sectional view illustrating the use of the clip shown in Fig. l

Fig. VII represents u perspwztivo view illustrating the use of another modified form of my invention.

Fig. V HI represents :i sectional view of another form thereof.

Fig. IX represents a fragmentary View illustrating the use of the form, shown in Fig. VIII.

Fig. X represents a sectional view of air other niodificatlon.

Fig. XI illustrates dii'ierent, modification.

lielf etrlng specifically to the drawings. in H and ill, I have shown the metallic frame 1, which has secured to it in the usual manner the end piece ineinheir i2, circling the frame 1 and extending entirely therearound, should he understood by rot erenee to Fig. I, is the non-metnllh: frame member 3. To retain the frame member in position 1' preferably make use oi the washer member 4 having the recess us at 5 to fit around the frame 1, end having a pair of upwardly extending fingers (3 provided with hooked terminal portions urlupted to bite into the ends of the frame 3.

in use the frume 3 is out to the proper length to fit around the outside of the frame 1 and has applied to each end the washer member at with its lingers (S forced to bite into the zylouite firmly interlock therewith in the same nntnnor as do the hooked ends illusl'rauied in eonnection with Fig. V1, end suitable screws or other fastening devices 2' are then passed outward through the end pieces 2 to intercugruge with the threaded aperture 8 in the washer member or cap plutc at to secure the plate l to the cor pie .2 and hy drawing it the use of at slightly tightly against the end piece to drew the frame 3 around the frame 1.

The form illustrated in Figs. to V1 is substantially the some it? the one just described, with the exception tlmt the lingers 6 in phu-o o'l' heinn at the sides of the late or washer 4 are placed one on the outer edge and the opposite one at the center of the notch 5, one advantage of thisconstruction being that the inner prong 6 will lu-nd up into the groove adapted to receive the Frame 1 and consequently will he enlirely invisible. while the other prong or linger l3 will lie along: the outside of the frame section ll and will he u'ueticully iurisihle when the moduling is viewed from the front; a further udvuntun'e being that this outer prong will hold down lho extreme end of the non-nu:- itullic frame and cause it to more snugly iii; in pluce.

l huve illustrated :1 further anoa'lilicutiou of my invention in connection with Fig. Vii, in which the pi; e has risiu thereifrou: the standard mesh-er l tor-minding in the hand or cross pier-e l0 uilupted to he while en and its hooked ends to bent around the non-metallic frame 3. It will thus be seen that the standard 9 preferably fitting in a slight groove in the outer face of the frame 3,'l10lds it down at the bottom, while the portion 10 fitting around the non-metallic frame securely anchors the several parts together. i

As a further modification of my invention I have illustrated in connection with Fig. VIII a central terminally split prong member 11 as rising from the plate 4: and adapt ed to be centrally embedded in the terminal portion ofthe frame 3 to lock the plate 4 thereto.

FigiX illustrates a form in which the plate :or anchoring portion l2vfits against the inner face of the member 3, while a screw 13 passin r through the plate 12 and into the frame 3 serves to lock the parts together.

Fig. XI illustrates'another form in which in place of the plate 12 a prong or finger 14 is employed which grips into the portion 3, while the securing screw. 7 extends upward centrally into the end of the member 3 and locks it against outward movement. Thus in this form the plate and its prong 14 serve to hold the member 3 down toward the end piece, while this holding action is supplemented by the screw 7 which also looks the end of the member 3 against outward movement away from engagement with the the parts very securely held in place.

having a washer-like portion adapted to be secured to a metallic -frame and having lat; orally extending portions adapted to bebent .at right angles thereto to grippingly engage a non-metallic member.

2. A device of the character described in eluding a holding'member for non-metallic secured to a metallic frame and having laterally extending portions adapted to be bent at right angles thereto and spur members formed at the ends of the laterally extending portions to grippingly engage am metallic member.

In testimony whereof I have aifixed my signature, in presence of two witnesses.
